Psychological and physiological effects of visual stimulation with real plants and artificial natural structures: A study protocol for a randomised controlled trial

Abstract

Although many studies demonstrate the positive effects of the natural environment on human health, it is not always possible to use real natural environments or plants in healthcare settings. The authors designed artificial natural structures based on fractal geometry. They present a study protocol aimed to investigate the artificial natural structures' effect on different variables (stress, emotions, pulse, and blood pressure) in humans.
